Study Notes
Unifying Themes in Biology
- A unifying theme in biology is evolution, which explains the unity and diversity of life by describing how all species share a common ancestor and have evolved over time through natural selection.
Role of Genes in Organisms
- Genes, made up of DNA, carry information needed to construct and maintain an organism's traits and characteristics.
- They play a crucial role in determining the development, growth, and function of an organism.
Scientific Method in Biology
- The primary function of the scientific method in biology is to develop and test hypotheses, making it possible to understand and explain the natural world through observation, experimentation, and evidence-based reasoning.
Levels of Organization in Biology
- Molecular biology, the study of biological molecules, such as DNA, proteins, and membranes, is carried out at the molecular level of organization.
Origin of Life on Earth
- The timeframe for the emergence of life on Earth is estimated to be around 3.5-4.5 billion years ago, during a period known as the Hadean Eon, when the planet's environment was still hostile and undergoing significant changes.
